Sara Zeimer advises clients on litigation matters in multiple areas, including toxic torts, pharmaceuticals, product liability, and environmental actions. She represents clients, from emerging start-ups to Fortune 500 companies, before state and federal courts. 

Sara is adept at identifying pathways to resolve client disputes before the need for litigation; however, if litigation is unavoidable, her extensive experience as a law clerk and now an attorney proves invaluable to clients. She handles all aspects of litigation, including research, fact and expert discovery, and motions practice, including drafting discovery requests and responses, motions in limine, Dau bert briefs, as well as other briefs and pleadings.

Prior to joining Keller and Heckman, Sara was a litigation associate in private practice where she focused on commercial civil litigation and criminal defense. Her extensive trial experience includes meeting with expert and lay witnesses, conducting witness examinations, and presenting an opening statement in a state juvenile proceeding. She represents clients before federal and state courts and in arbitration proceedings. 

During law school, Sara interned for the Honorable Andrew Y.S. Cheng at the San Francisco Superior Court, the San Francisco City Attorney’s Office, and the United States Department of Justice (DOJ) Office of Immigration Litigation (OIL). She also served as a Board Member for the UC Hastings Moot Court team (ranked #1 in the nation), where she finished as a semifinalist in the UC Davis Asylum & Refugee Law National Moot Court Competition, and an octofinalist in the Thurgood Marshall Memorial Moot Court Competition.
